Design of 5G mm-Wave Base Station Antenna Based on Multilayer PCB Technology

In this paper, a differentially-fed ±45˚ dual-polarized millimeter wave (mm-Wave) broadband antenna based on multi-layer PCB technology is proposed. The proposed antenna consists of two pairs of differentially-fed network, four cut-corner feeding stubs, a driven patch, and four parasitic patches. Th...

Description
Summary:In this paper, a differentially-fed ±45˚ dual-polarized millimeter wave (mm-Wave) broadband antenna based on multi-layer PCB technology is proposed. The proposed antenna consists of two pairs of differentially-fed network, four cut-corner feeding stubs, a driven patch, and four parasitic patches. The stacked parasitic patches can increase impedance bandwidth and antenna gain. Furthermore, a 2×2 antenna array is designed. Both antenna element and antenna array employ standard multi-layer PCB technology. The simulation results show that the proposed antenna covers the widely used 5G band (24.25-27.5 GHz), and each port isolation reaches more than 30 dB. Therefore, the proposed design could provide a great candidate for 5G mm-Wave base station applications.
